Teaching NeuroImages: Giant cell arteritis presenting with acute ischemic strokes due to diffuse intracranial stenoses
A 72-year-old woman with unremarkable medical history was admitted with acute ischemic strokes (AIS) in multiple arterial distributions in anterior and posterior circulation (figure 1A and supplemental data at Neurology.org). Elevated erythrocyte sedimentation rate (98 mm/h) prompted the evaluation of superficial temporal arteries (STA) with duplex sonography (halo sign; figure 1B) and contrast angiography (right STA [figure 2A] and multiple intracranial arterial stenoses [figure 2, A–D]). STA biopsy confirmed the diagnosis of giant cell arteritis (GCA; figure 1, C and D).

Some light in the shadows of atrial fibrillation and stroke: To look or not to look
In ischemic stroke, the diagnostic workup determines the best preventive strategy. However, cryptogenic stroke accounts for about 20%–40% of all strokes.1 For these patients, the best preventive treatment remains unknown, and most guidelines recommend risk factor modification and antiplatelet therapy. Given the substantial recurrence rate for cryptogenic stroke, this is not a comfortable situation: just try to tell your stroke patients, "After all these tests, I do not have any clue why you had a stroke"; and about the treatment, "Just take an aspirin and cross fingers you do not have another one."

Striving to improve the quality of stroke care in the USA
Compelling evidence indicates that the organization and delivery of stroke care makes a difference in the chances of patients surviving, their level of disability, and the chances of further strokes. Most evidence-based interventions do not require expensive high-technology medicine but rather need well-organized basic care delivered by people with expertise in stroke. Yet there are many places in the world, including parts of the United States, where high-quality care cannot be guaranteed, resulting in higher than necessary levels of mortality and morbidity.

Relevance of supraventricular runs detected after cerebral ischemia
Conclusions: Patients with cerebral ischemia and SV runs had more recurrent strokes and numerically more novel AF during follow-up and could benefit from further prolonged ECG monitoring. pAF detected after stroke is not a temporal phenomenon.

Outcome after stroke thrombolysis in patients >80 years treated within 3 hours vs >3-4.5 hours
Conclusions: In this observational study, unselected patients >80 years of age treated with IVT after 3 hours vs earlier had a slightly higher rate of SICH and similar unadjusted functional outcome but poorer adjusted outcome. The absolute difference between the treatment groups is small, and elderly patients should not be denied IVT in the later time window solely because of age without other contraindications.

Nonlinear temporal dynamics of cerebral small vessel disease: The RUN DMC study
Conclusions: SVD progression is nonlinear, accelerating over time, and a highly dynamic process, with progression interrupted by reduction in some, in a population that on average shows progression.

Quality improvement in neurology: Stroke and Stroke Rehabilitation Quality Measurement Set update
Stroke is the fifth leading cause of death in the United States and the second leading cause of disability worldwide.1,2 "On average, every 40 seconds, someone in the United States has a stroke, and someone dies of one approximately every 4 minutes."3 Each year, nearly 800,000 people experience stroke, with up to 185,000 experiencing recurrent stroke events.3 Strokes occur at any age, and risk increases with age.4 Nearly half of older stroke survivors experience moderate to severe disability.5

Swallowing-induced displacement of the carotid artery as a risk of stroke: Flip-flop phenomenon
A 70-year-old man without cerebrovascular risk factors was admitted to our hospital with amaurosis fugax of the right eye. Diffusion MRI showed an acute asymptomatic brain infarct in the right frontal lobe cortex, and carotid duplex ultrasound revealed movement of the right internal carotid artery (ICA), with a hypoechoic plaque at its origin, in contact with the hyoid bone during head rotation and swallowing (figure).

TIPIC syndrome
A 31-year-old woman presented with left acute cervical pain. Cervical imaging showed a large pericarotid infiltration (figure 1). A diagnosis of transient perivascular inflammation of the carotid artery (TIPIC) syndrome was made. The patient received steroids with full clinical recovery 12 days after onset. The follow-up ultrasound showed striking decrease of the perivascular infiltration, confirming the diagnosis (figure 2).

Teaching NeuroImages: Typical neuroimaging features in high-altitude cerebral edema
A 61-year-old man presented with thunderclap headache followed by loss of consciousness, 2 days after arriving in Atacama Desert, Andes Mountains, Chile, at 4,000 meters. Examination showed coma. Mechanical ventilation was necessary. He had progressive improvement after transfer to low altitudes. Brain MRI showed diffuse vasogenic edema and microhemorrhages (figure), and high-altitude cerebral edema (HACE) was diagnosed.

Sickle cell disease and the unmet challenges of neurologic complications
Sometimes an important scientific report is more notable for what it cannot tell us than for what it can. In this issue of Neurology®, Noubiap and colleagues1 provide a comprehensive, well-conducted systematic meta-analysis of the neurologic complications of sickle cell disease (SCD) that incorporates rigorous design and advanced analytic methods to delineate in substantial detail what is known about the prevalence of neurologic injury among people with SCD in Africa—where over half the world's population of people with SCD reside. As one might expect, based upon what is known from more medically developed region...

Functional impairments for outcomes in a randomized trial of unruptured brain AVMs
Conclusion: Death or stroke with functional impairment in ARUBA after a median follow-up of 33 months was significantly lower for those in the MM arm both as randomized and as treated compared with those with IT. Functional severity of outcomes was lower in the MM arm, regardless of Spetzler-Martin grades. ClinicalTrials.gov identifier: NCT00389181. Classification of evidence: This study provides Class II evidence that for adults with unruptured brain AVMs, interventional management compared to MM increases the risk of disability and death over 3 years.

Neurologic complications of sickle cell disease in Africa: A systematic review and meta-analysis
Conclusions: The burden of neurologic complications of SCD is important in Africa and most likely underestimated. A better evaluation of this burden requires larger prospective studies using standard up-to-date screening methods. Accessibility to diagnostic tools such as neuroimaging, transcranial Doppler, EEG, and neuropsychological evaluation, as well as to preventive and therapeutic interventions and trained health care providers, should be improved in routine clinical practice.

Procoagulant imbalance in premenopausal women with chronic migraine
Migraine has been associated with an increased risk for stroke, especially in young women.1 Among the pathophysiologic mechanisms linking migraine and stroke, coagulation abnormalities have been regarded as a logical link.2

Serpiginous cranial arterial calcification in uremia
A 65-year-old man with chronic kidney disease (CKD) on hemodialysis presented with a subcortical stroke. Unenhanced CT scan of the brain revealed widespread arterial calcification, notably involving the carotid siphons (figure 1) and external carotid artery branches (figure 2, A and B). Vascular calcification in CKD closely resembles ossification, and may involve the intima (as in atherosclerosis) or more commonly the media.1 Both patterns of calcification are associated with increased cardiovascular mortality, though no specific treatment has been shown to modify this risk.2 This example is particularly striking for the s...
